Server-side HTML vs. JS Widgets vs. Single-Page Web Apps

Server-side HTML vs. JS Widgets vs. Single-Page Web Apps | JavaScript for Line of Business Applications | Scoop.it
From blog.pamelafox.org - May 11, 2013 4:50 AM

At the recent GOTO Chicago conference, I gave a talk on "Frontend Architectures: from the prehistoric to the Post-modern." In just my first 10 months at Coursera, I've experienced the joys and woes of many different frontend architectures, and I wanted to share what I learnt. I detail everything in the slides, but I'll summarize my thoughts here as well.

How do you pick an architecture?

We could make our decision by just checking Twitter and seeing what all the cool kids are talking about, but uh, let's pretend that we're more scientific about it than that, and figure out whats important to us as web developers.

Modern Ember.js Application Workflow with Yeoman and Mocha

Modern Ember.js Application Workflow with Yeoman and Mocha | JavaScript for Line of Business Applications | Scoop.it
From tech.pro - May 10, 2013 5:38 AM

The following tutorial will provide an overview for building Ember.js applications with Yeoman. Keep in mind, Yeoman is a framework agnostic collection of tools, used to manage the workflow of any JavaScript application or plugin. For the sake of this tutorial, we have chosen to focus on Ember.js, as a case study.

Our workflow would not be complete without also setting up our testing strategy, so we will also include a standard BDD (Behavior Driven Development) setup with the Mocha testing framework.

SPServices is a jQuery library which abstracts SharePoint's Web Services and makes them easier to use. It also includes functions which use the various Web Service operations to provide more useful (and cool) capabilities. It works entirely client side and requires no server install.

generators in v8 - think await in C#

From wingolog.org - May 9, 2013 3:44 AM

Andrew asked if me if we could somehow make asynchronous programming easier to write and read, maybe by implementing something like C#'s awaitoperator in the V8 JavaScript engine. I told him that the way into V8 was through standards, but that fortunately the upcoming ECMAScript 6 standard was likely to include an equivalent to await: generators.

JS Drip #17: Boiling Down Arrays with Array#reduce

JS Drip #17: Boiling Down Arrays with Array#reduce | JavaScript for Line of Business Applications | Scoop.it
From us6.campaign-archive1.com - May 6, 2013 3:39 PM

We've talked before about the advantages of using Array's higher order functions (likemap and sort) rather than manually iterating over an array's contents. But unlike mapand sort, which produce new arrays, reduce can boil an array down to a new value of any type.

Why Hasn’t Agile Or Scrum Improved My Software Development?

How to Diagnose Why Scrum “Isn’t Working”

 

A lot of software development teams switch to Agile development in order to solve some immediate problems they are experiencing.  A few sprints in, it becomes clear:  the problem wasn’t solved.  It’s easy to want to throw in the towel and go back to your old software development methodology.  Yeah, there were problems before, but it felt like you knew the scope of your team’s problems.

What Your Job Descriptions Are Saying to Developers About Your Company

What Your Job Descriptions Are Saying to Developers About Your Company | JavaScript for Line of Business Applications | Scoop.it
From www.daedtech.com - May 2, 2013 3:40 PM

 One relatively common characteristic is that below the actual text of the email is pasted a job description. More often than not, I read this (or at least start to) out of general curiosity as to the state of the market. Some of them are reasonable and straightforward, making me think that the company in question would be a good, or at least decent, place to work. But others contain things that I’d call red flags.

Extrapolating beyond what gets sent to me via secondhand emails and generalizing to job boards and sites and other places where companies solicit talent (I can’t speak directly to these since I haven’t looked at them in quite a while), I think companies would be well served to consider what their job descriptions say to developers about them. It may not always be what’s intended.

Today, ECMAScript 6 is in the process of being finalized. ECMAScript is the foundation of JavaScript and, hence, exploring the proposed features today also means that we get a sneak peak at how we will be writing JavaScript in the near future! In this article, we’ll explore ten new features, with a significant focus on tools, browsers and transpilers.

Object.create(): the New Way to Create Objects in JavaScript

From www.htmlgoodies.com - May 6, 2013 8:49 AM

There are a lot of ways to create Objects in JavaScript, perhaps even more to integrate inheritance into them. Just when you thought that you've seen every possible way to create JS objects, I'm here to announce that there's yet another: the new Object create() method. Wouldn't you know it, there are some pretty good reasons to use it. But before we get into that, let's get familiar with how it works.

The future is written in Javascript

From www.gullicksonlaboratories.com - May 4, 2013 4:28 PM

There are a lot of programming languages, but there is only one that runs in your web browser, and that’s Javascript. Ruby, Java, C#, Python, PHP and dozens more are used to write software for the web but in the end they all produce HTML and Javascript, and HTML is not a programming language. That means that there’s only one programming language for the web, and that’s Javascript.

If you’re writing software for the web, you’re programming in Javascript, it’s just a matter of how many layers of “comfort zone” there is between you and your application.

Why Discourse uses Ember.js

Why Discourse uses Ember.js | JavaScript for Line of Business Applications | Scoop.it
From eviltrout.com - May 2, 2013 3:38 AM

* Ember.js is not that big. It’s 47k minified and gzipped. If you think that’s too big, consider the image of Thomas on his own web site is 49k.

* Discourse only requests JSON when you change views. On your initial visit it actually includes the JSON payload in the body so it doesn’t need to make an additional request.

* Nobody compiles templates in production. In development mode while you are changing them, they get compiled, but when you deploy you pre-compile them for performance.

* I’m not sure why you’d have to query data once you’ve already requested the JSON, but I suppose some times you might download a list of objects and then only show ones that are active or something. This isn’t a common case, and even if it was, isn’t it better than a server round trip to change the filter?

* Generating the HTML string is something that has to happen. And he’s not wrong, it is slower than just getting the HTML from the server. In particular, on low powered devices you will notice that rendering is slower than regular HTML. However, I’d offer two rebuttals to this: 1) Javascript and devices are only going to get faster in the future – the latest iPad renders discourse very smoothly – and 2) It can often be faster even with slow rendering to send much less data across the wire. Consider a table view with many controls on each row. Why send the html for all those buttons across the wire for every row? You can send the basic row data and the renderer decorate it.

Author In ES6, Transpile To ES5 As A Build-step: A Workflow For Grunt

Author In ES6, Transpile To ES5 As A Build-step: A Workflow For Grunt | JavaScript for Line of Business Applications | Scoop.it
From addyosmani.com - April 30, 2013 7:38 AM

Today I used a Grunt task called grunt-traceur by Aaron Frost to author code in ES6 (maximally minimal classes, modules, rest params, spread operators) and transpile back to ES5 as a build-step. It felt fantastic and the final product now runs in all modern browsers.

 

I also played with grunt-es6-module-transpiler which let me target CommonJS or AMD as readily usable compile-targets for my modules. Both projects enable us to use JavaScript.next features in our apps before support actually lands in browsers. Judging by the ES6 compatibility table by @kangax this may still take a while so transpilation is an interesting option worth considering.
